Safety Rules Regarding Digital External Flash Use

Using a digital external flash can create great photographs,
especially at special events. The external flash also allows you to
adjust the height of the flash, and control the bounce of the light.
There are a few things that should be considered to maintain the safety
when using these devices.

Direct Eye Contact

Direct eye contact with the external flash should always be avoided.
An external flash creates a very intense light and can damage the
subjects vision. Always make sure the subject is looking at the camera,
and the flash should not be placed close to the lens.

Testing

It's a good idea to test the flash before you use it. When you test
it, be sure it's pointed away from everyone. You don't want the flash
to accidentally fire into someone's eye line.

Taking It Apart

It may be tempting to take the flash apart to see how it works or to
fix it. This is best left to a professional. Not only could you damage
the flash unit, you can cause yourself injury. The external flash unit
requires high voltage to operate, and it can be very dangerous if you
take it apart.
